Topic: Fallback mail server
it is possible to forward mail that have this error to another mailserver?
"Sender address rejected: User unknown in virtual mailbox table;"
What were looking for is something like this...
email --> iredmail server --> if there *is* an account, then deliver locally
email --> iredmail server--> if there's no account, then forward to another smtp.
I have tried with postfix fallback_transport but i cant get it to work.
